Abstract

Areca nut and products made from the nut, evaluated by the International Agency for Research on Cancer as carcinogenic to humans since 2004, are being increasingly used in India and South East Asia and exported to many countries. There is thus an urgent need to identify best control policies and research gaps. On 1 February 2018, a group of experts shared their latest knowledge and perspectives on areca nut at Healis-Seksaria Institute for Public Health in Navi Mumbai, Maharashtra, India. By itself, areca nut has been implicated in oral and oesophageal cancer. Areca nut users are also at high risk of oral submucous fibrosis, a debilitating and potentially malignant condition. Users may also suffer adverse health outcomes due to smokeless tobacco, commonly mixed with areca nut. The use of areca nut commonly begins in childhood and often proceeds to use with tobacco. Gutka, a widely consumed, industrially made areca nut product containing tobacco, has been banned in all states and union territories of India, but it is still widely available. Areca nuts contain arecoline, an alkaloid that stimulates various brain receptors, promoting physical dependence. Areca nut alkaloids have also been implicated in carcinogenesis. Other chemicals, introduced during cultivation and processing of areca nuts, contribute to oral submucous fibrosis and cancer. The wide variety of products, different storage conditions and lack of regulation can lead to significant variation in the content of toxicants, carcinogens and alkaloids, making the psychological and physical dependence issues even more challenging. Regulation of product contents is needed as a part of control measures to supplement product bans.
